BRAKE-HIGGINS: FOR SELF-PROPELLED VEHICLES- Specification of LettersPatent.

Application filed May 9, 1905. Serial No. 259.607.

To all whom it may concern:

Be it known that I, CHARLES O. SNYnEn, a citizen of the United States,residing in the city of New York, in the borough of Manhattan and Stateof New York, have invented certain new and useful Improvements inBrakeRigging for Self-Propelled Vehicles, of which the following is afull, clear, and exact description.

This invention relates to the brakerigging of self-propelling vehicles.

In that class of vehicles where the brake in the form of a strap orshoes acting upon a.

This invention isdesigned to overcomethis defect, and to that endconsists in so mounting the stationary members of the brake that thestrain referred to is communicated to the body of the vehicle instead ofto Y the sleeve mentioned and at a point where it will be distributed ina downward direction throughout all of the springs of the vehicle.

In the drawings accompanying and form ing a part of this specification aform of my invention is illustrated, wherein- Figure 1 is an elevationof a portion of an automobile, illustrating a practical embodiment ofmy'invention. Fig. 2 is a similar view with the wheel and spring removedand the brake-drum shown in longitudinal section. Fig. 3 is an enlargedView of the end of the brake-carrier, certain parts being broken awayand shown in longitudinal section. Fig. 4 is a top plan view of partsshown in Figs. 1 and 2, certain parts being shown in horizontal section;and Fig. 5 is a view from the end in about the line 5 5 of Fig. 4.

Only such portions of the vehicle have been illustrated as are necessaryto a complete understanding of the invention.

The bottom framingnmember 11 is in'the present instance a channel-ironhavin a web portion 12 and two horizontally-disposed flanges 13 13. Thisis the usual floor-beam of the car or carriage and from which the theparts are supported. The wheel designated in a general way by 15 may beof any convenient construction, having a brakedrum 16 secured thereto,which brake-drum, in the present instance, is intended for engagementupon the inner perimeter by a pair of rake-shoes 17, each 0 whichconstitutes a half-circle, and is provided in the form illustrated withan eye 18 at its. lower end. Such eyes are pivoted by means of a pivotmember 19, and their upper ends are controlled by a toggle comprising apair of links 190, having suitable connections with the free ends of theshoes. Such links are pivoted at their knuckles to a link 20, which isin turn pivoted toa rock-arm 21, carried by a rockshaft 22. Therock-shaft 22 and the pivot member 19 are carried by a brake-carryingdevice 25, which brake-carrying device is, in the present instance, inthe nature of .a channel-iron or truss, it having a web portion 26 andhorizontally-disposed flanges 27 to give it stiffness and rigidity, andfor the purpose of lightness it may be of skeleton work, as shown.

The axle-30, to which the wheel is fast and whichwill be driven in somesuitable manner, has a sleeve 31 surrounding it, which sleeve carries abearing-box 32, containing the usual rollers or other bearing devicesfor the axle. There is a sleeve 33 loose upon the sleeve 31 and heldfrom longitudinal movement by means of a collar 34. -The sleeve 33 has aflange 35 which may be fastened, as by rivets 36, to the end oftliebrake-carrier and surround an o ening 37 in such brake-carrier, whichmay e concentric with the sleeve 31 and axle 30. Assuming that the rearaxle is the one illustrated, the brakecarrier will project forwardly andinwardly tothe bodybeam and be secured thereto in some suitable manner.In the present instance a bracket 40, having side members 41 to fit uponthe side of the beam, may be secured b means of bolts 42 to the same, asuitable illing 43 being inserted in the hollow portion of thechannel-iron to give greater stability to the bracket. The connectionbetween the end of the brake-carrier and the bracket may be .by means ofa turnbuckle 44, engaging a screw-threaded rod 45 from the end of thecarrier, and a screw-threaded rod 46, having an e e 47, surrounding aivot 48 in' the brac et 40." The turnbuc e affords means of adjustment,and the pivot will permit movement of the carrier when the axle andwheel move vertically with relation to the body. The spring 50 is shownresting upon the sleeve 31 and fastened to the same by means of clips53. Its forward end is supported by bracket through the link 51 and arm52. All the parts of the brake controlled by the carrier areconcentrically mounted upon the sleeve, and consequently in similarrelation to the wheel and its brake parts. The a plication of the brakewill be b means of a l ver' 55, fast upon the rock-s aft 22, upon movingwhich to straighten the toggle the brake-shoes will be forced intoengage ment with the brake-drum. The twisting strain thus brought uponthe shoes will now be-transmitted to the brake-carrier 25, and thismember being pivoted about the axle will tend to swing downward at itsforward end, which tendency will be exerted upon the middle of theVhlClel)O(l V, and thus distributed evenly throughout the springs. Afootboard 60 may be carried by a bracket 61, also dependent from thebracket 40. By this means one substantial bracket may e at tached to theframing member of the. vehicle in a strong manner and the multiplicityof attached devices be obviated.

In Fig. 3 a bracket 63 is shown for carrying the rock-shaft 22, suchbracket being fastened by rivets 64 to the horizontal member of thecarrier and by rivets 65 to the web member thereof, and the bracket 66for carrying the pivot member 19 may be suitably riveted or bolted tothe. frame of such carrier and receive the enlarged portion 67 of saidpivot-pin. The brake-carrying lever 25 will serve to'a certain extent asa radius-bar.

Various details of construction may of course be changed as variouscondu'nims of I employment demand without departing from pivoted to saidradius-rod, and having a link connection with said shoe, and means forim parting tension to said lever.

2. .In a brake-rigging, a rotating drum. a radiusrocl attached to thevehicle-body and extending into proximity to said drum. a pair ofbrake-shoes pivoted to said radiusrod and extending peripherally aroundthe drum in opposite directions, and a lever also pivoted to saidradius-rod and having a pair of link connections to the respectiveshoes.

3. In a brake-rigging, a rotating drum lixed to the vehicle-wheel, aradius-rod attached to a portion of the vehicle-body and extending intoproximity to said drum. said radiusrod being formed of a pair ofdiverging truss members. having an intermediate web with perforations oropenings therein, a lever piv oted within said radius-rod, a brake-shoehaving a link connection to said lever, and means for pivotallyconnecting said brakeshoe to said radius-rod.

In witness whereof I subscribe my signa ture in the presence of twowitnesses.
